What is there in common between the different types of stroke? Learn more about the different types existing, what are the causes and main symptoms.
When talking about types of stroke, the first thing that we remember is of myocardial infarction. However, there are several types of stroke, all with their characteristics, with their severity, their causes and symptoms. However, although they are all different, all have something in common. In all of them, what we see is an absence of blood circulation in one or more arteries, which leads to serious consequences.
Of all types of stroke, that presents numbers more troubling is the infarct of the myocardium, however they all cause problems and may have serious consequences.
So let’s understand what are the main types of stroke and to know each one of them.
THE 5 TYPES OF STROKE: INFORM YOURSELF CORRECTLY
1. MYOCARDIAL INFARCTION
Known mostly as heart attack, stroke occurs in the heart muscle that has the name of the myocardium. This muscle has the main function to send the blood to the entire body, causing it to reach all the organs and tissues. This muscle is irrigated by the coronary arteries, which are responsible for to do to get to the heart the nutrients and oxygen needed. When this irrigation is affected due to a blood clot that interrupts the circulation in the coronary arteries is called myocardial infarction. Thus, cells in this affected zone, can die.
When this problem is not treated in time, the muscle will eventually die and as we know, the heart is the engine of our entire body and without it we could not live. Therefore, the myocardial infarction is one of the types of myocardial the most serious and emerging, and should be treated in a hospital as soon as possible.
The most common symptoms in this type of problem are:
- Intense pain in the form of a grip or burn;
- Pain in the left arm, jaw, neck and sometimes on the back;
- Heart rate and breathing are accelerated;
- Dizziness and weakness;
- Nausea and vomiting;
- Loss of consciousness.
- MYOCARDIAL BRAIN
Clarified the myocardial infarction, it is important to explain the difference to an infarct the brain, or more correctly a Cerebral Vascular Accident (STROKE) seen that according to the University Institute of Lisbon, about 25.5% of the Portuguese don’t know the difference between these.
A STROKE is a problem sudden where the visible effects and senses are immediate, once that occurs in the brain and this controls everything we do, think, feel, or even how we communicate. So, this occurs when the blood supply to a part of the brain is prevented, due to the blockage of an artery that takes blood up to this.
The STROKE can cause the death of this damaged portion of the brain tissue, which is called then of a heart attack of the brain. The main symptoms undergo difficulty in moving the face, the arms and legs, difficulty speaking and expressing themselves and even vision problems.
The risk factors of this problem are the same of myocardial infarction:
- Cholesterol high;
- Consumo excessivo de bebidas alcoólicas.
- ENFARTE INTESTINAL
A myocardial bowel, such as in other types of stroke, occurs when there is a deficient irrigation of a part of the intestine due to clogging of a blood vessel by a blood clot.
When there is a lack of blood and oxygen to a part of the intestine, this end up dying. As the name of the thrombosis intestinal or mesenteric ischemia indicates that there is a swelling in the affected area, due to the gases accumulated produced and proliferados by the bacteria. When this swelling is too much, this part of the intestine eventually break, releasing blood and causing an infection very serious. This ischemia can occur gradually, which gives the name of mesenteric ischemia, chronic, or sudden, call mesenteric ischemia acute.
The symptoms can arise suddenly or can develop slowly over several days. The most common for this type of stroke are:
- Abdominal pain, which worsens over time;
- Sensation of swelling in the belly;
- Nausea and vomiting;
- Fever above 38 ° c;
- Diarrhoea with blood in the stool;
- Weight loss.
In contrast to the other strokes are discussed, infarct of the bowel is not an emergent situation, however, if the abdominal pain is very intense and does not improve after 3h, the trip to the hospital is mandatory with the aim to confirm the medical diagnosis and start as soon as possible the treatment to avoid that a large portion of the intestine is affected.
- PULMONARY INFARCTION
Also known as a pulmonary embolism or thrombosis pulmonary, pulmonary infarction is necrosis, or cell death of lung tissue due to lack of blood circulation.
The lung has two sources of irrigation, the pulmonary arteries and the arteries in the bronchial, soon, when we have a blockage of an artery, usually does not occur myocardial, once the integrity of the fabric remains due to the other artery is not obstructed. So we have this ischemia called pulmonary thromboembolism. However, due to several other factors such as heart failure, this ischemia can turn into pulmonary infarction, corresponding to 10% of the total cases.
What happens is that a blood clot lodges in a blood vessel in the leg or in the pelvis, it clogs it and prevents the passage of blood. When this clot breaks free and passes into the bloodstream, it is customary that if you scroll to the lungs. This results in a severe pain when breathing, cough with sputum and blood as well as breathing difficulties.
The greater the breathing difficulty, minor amounts of oxygen circulating in the blood, and may even affect all the organs of our body that need a good oxygenation to perform their functions properly.
Note that, as in all types of stroke, this happens when there is a single blood clot in a blood vessel. The situation worsens drastically when there are multiple clots, or when the infarct extends for a long time.
5. MYOCARDIAL THE SPINAL
This heart attack has the name syndrome ischemic acute of the spinal cord, is a very rare disease with a prevalence of 1 to 2% of all acute diseases of the central nervous system.
Occurs mainly due to diseases of the abdominal aorta in cases of aneurysms, hernia, bulky, arthritis, states, late syphilis or in cases of tumors that cause compression to blood, being that most of the causes are not always known.
Which occurs in this pathology is the lack of blood supply to a segment of the spinal cord, usually the segment of the dorsal artery of Adamkiewicz and artery the spinal cord.
Important to know that the vertebral column is divided into three parts, being that this pathology can affect the first two-thirds are irrigated by the arteries spinal earlier.
The symptoms of this type of stroke are, in the vast majority, a pain, intense and sudden in the back, leading to a weakness flaccid bilateral that quickly extends to the legs, due to the location of the spinal cord that was affected, with high loss of thermal and pain sensitivity.
